US Patent:

42592305, Mar 31, 1981

Filed:

Sep 26, 1979

Appl. No.:

6/079105

Inventors:

Donald M. Simons - Wilmington DE

Assignee:

E. I. Du Pont De Nemours and Company - Wilmington DE

International Classification:

C08K 334

US Classification:

260 4246

Abstract:

Polypropylene compositions having high ignition resistance, flex modulus, and impact resistance are obtained by blending polypropylene homopolymer, a propylene/ethylene copolymer, an EPM or EPDM elastomer having an ethylene content of about 50-65 weight percent and a Mooney viscosity of 35-80, mica, a commercial chlorinated fire retardant, and antimony trioxide in defined proportions. These compositions are particularly suitable for electrical wire insulation and other applications where toughness, stiffness, and ignition resistance are important.

G01N 100

US Classification:

424 88

Abstract:

Estriol and estradiol glycidyl ethers, immunogenic conjugates thereof and processes for their preparation are provided. The immunogenic conjugates are useful for eliciting and purifying antibodies and in performing immunoassays for estriol and estradiol.

Filed:

Feb 12, 1993

Appl. No.:

8/029971

Inventors:

Donald M. Simons - Wilmington DE
Susan Y. Tseng - Hockessin DE
David M. Obzansky - Elkton MD

Assignee:

E. I. DuPont de Nemours and Company - Wilmington DE

International Classification:

G01N 33543

US Classification:

436518

Abstract:

Immunoassays and DNA probe assays utilizing a non-immune, reversible binding displacement system are provided. In the assay, a releasable ligand, a binding partner for the releasable ligand, an analyte of interest, an analytically detectable (reporter) group, and at least one binding partner for the analyte, are first attached to an insoluble phase so as to form reporter-labeled complex bound to an insoluble phase, followed by the addition of a displacer ligand which displaces the releasable ligand along with some portion of the reporter-labeled complex, so that the released reporter is analytically detectable in a free liquid medium and can be related to the concentration of analyte in the sample.

Filed:

Appl. No.:

6/201075

Inventors:

Donald M. Simons - Wilmington DE

International Classification:

C08K 532

US Classification:

252606

Abstract:

Certain filled propylene polymer compositions, especially propylene homopolymers filled with a carbon black (10-50 parts per 100 parts of polymer) and containing about 30-50 parts of intumescent fire-retardant obtained by heating a mixture of a polyol, a phosphorus acid, and melamine have very high ignition resistance and desirable physical properties. When usual inorganic fillers are used, instead of carbon black, good ignition resistance is not obtained. Carbonaceous materials other than carbon blacks, for example, acetylene blacks, graphite, and so-called Austin black reduce or completely counteract the fire-retardant activity of the intumescent fire retardant. Filled propylene polymer compositions of this invention are particularly suitable in applications where the fire hazard is particularly great, for example, in automotive parts under the hood and in electrical applications.
